SEAL-LOCK FOR CAR-DOORS.

SPECIFICATION forming part of Letters Patent No. 284,632, dated eptember 11, 1883.

Application filed May 4,1883. (Model) To all wham it may concern.-

Be it known that I, GEORGE J. HARTMAN, a citizen of the United States of America,

and a resident of Lake, in the county of Cook cally claimed.

As heretofore constructed, locks of a somewhat similar character to mine have been made with theeasing which contains the latch made open at the top; the portion of the latch sliding therein did not extend below the bottom thereof, and the hook thereon was not so located as to lie on the interior of the car. In my invention the top and exposed sides of the casing are closed 5 thelatch sliding therein 62(- tends below the bottom of the casing, and the hook for engaging with the cardoor latch lies back of the casing, and is shut in when the door is closed. I thus produce a fastening which is peculiarly fitted for action in case of snow and sleet, has the lock in a conspicuous place and easy of access, and in which the sliding latch is readily removed from the eX- ter'ior by pressing up beneath it.

In the accompanying drawings, Figure 1 represents a perspective view of the entire look as applied to a car; Fig. 2, a sectional elevation of the casing and latch put together. Fig. 3 is a section on line x m, Fig. 2, and Fig. 4 is a rear elevation of the casing and latch. Fig. 5 represents a side elevation of the latchcasing, and Fig. 6 a rear elevation of the same. Fig. 7 represents a side elevation of the latch detached, and Fig. 8a rear elevation of the same. Fig. 9 is a rear elevation of the doorhook, and Fig. 10 a plan view of the same.

Corresponding letters in the several figures of the drawings designate like parts.

A denotes the latch-easing, consisting of a casting formed sectionally V-shaped,with parallel .side walls and end wall, and open toward the rear, where its edges unite with the plate or flange a, that has screw-holes for securing the lock to the car-door post. The top of this casing is closed by a curved wall, while its bottom end is open. To the rear face of plate or flange a, at each side of the opening of easing A, is cast a projecting lug, b, that have holes bored for inserting a pin, 0.

D is the latch, which consists of a flat plate, shaped to fit into and vertically slide in casingA, with a forWardly-inclined upper edge, an upwardly-extended rear end, (I, and a lower parallel end, 6, forming a tongue that projects through the lower opening of the casing A, and is provided with a hole, f, for engaging the bow of a padlock. To about the middie of its rear edge this latch has a rearwardly-projecting side hook, g. This latchD is inserted into the casin g A through the rear opening of the same, so that the latchhook 9 proj ects rearward from plate or flange a, and so that its tongue 0 projects through the bottom opening of easing A, and in this position it is secured by the pin 0, passed through theholes in lugs b, and riveted in a manner that such latch will have a perfectly easy vertical sliding movement in such casing, and will drop to its lowest position therein byits own gravity. Small holes h are drilled through the side walls of easing A, just above the inclined upper edge of latch D when in its lowest position, for a sealing-wire to be passed through, that would be cut with a forcible upward motion of latch D, and'a slot, 17, is cast into the latch D, and slots j into the side walls of easing A, all of which slots will be in line with each other-when the latch is down, for inserting a strip of 'metal that is to be secured by a seal.

L is the hook-bar, that is secured to the end of the sliding car-do0r by'screws in a manner that, with closing the door, its pointed hook end I will engage with the under side of hook g, and will lift latch D until the square shoulders of hooks g and l have come vertically in line with each other, when such latch D will be released to drop by its gravitation, and interloekthe hooks g and Z, and thus lock the car-door.

For opening the car-door, the projecting tongue 0 of the latch D must first be pushed upward, whereby the hooks are disengaged. After the door is closed, so that the latch-hook g has been engaged with the hook I of the door, a padlock can be suspended to the projecting eyed tongue 6 of latch D, to prevent such latch from being lifted, and in addition a wire can be strung through holes h of the casing A, or a sheet-metal strip can be projected through the slots i and j for applying a seal, thus in-' suring against trifling with the car-door lock without detection. What I claim is- '1'. In a car-door fastening, an exterior casing, as A, adapted toreceive and guide a sliding latch, in combination with said latch, having a projection for working in said casing, and a hook, 9, formed on a rearward extension of said latch, which protrudes in beyond the surface of the car, and a door-catch, L Z, set on a line therewith, so that both latches will be shut in when the door is closed, substantially as set forth.

2. The car-door lock herein described, consisting of easing A, having plate or flange a, lugs I), with pin a, and openings for the receptionof sealing means, of gravitatinglatch 1), having hook g, and tongue 6, with hole f, and of door-hook L, the whole being constructed and arranged substantially as set forth, to operate as specified.

I11 testimony whereof I afiix my signature in presence of two witnesses.

GEORGE J. HARTMAN.
